| 20090258551 | OUTBOARD MOTOR AND HOOK ASSEMBLY USED FOR OUTBOARD MOTOR - A hook assembly is arranged to engage with an engaged member to fix a first housing to a second housing of an outboard motor. The hook assembly includes a rotation shaft, a hook member, a lever, and a weight. The rotation shaft is rotatably mounted on the first housing. A recessed portion is provided in the hook member. The recessed portion is arranged to open in first rotation direction. The recessed portion engages with the engaged member. The lever extends from the rotation shaft in a second rotation direction opposite to the first rotation direction of the recessed portion. The weight regulates the rotation of the hook member in the second rotation direction when the hook member and the engaged member are engaged together. The arrangement provides a highly-operable hook assembly for the outboard motor that prevents disengagement even when an obstacle collides with the outboard motor during traveling of a boat. | 10-15-2009 |
| 20100285704 | OUTBOARD ENGINE UNIT - An outboard engine unit having a cover halved into two. An undercover is made of a resin and halved into a left resin half and a right resin half. A lower mount cover is made of a resin and halved into a left resin half and a right resin half. The resin halves are formed so that when they are mated together, a gap is defined at a connection therebetween on a rear face side of the outboard engine unit. An elastic rubber member is filled in the gap. | 11-11-2010 |
| 20120115376 | ENGINE CASE OF OUTBOARD MOTOR - An engine case houses engines in the inside of the case and is provided with a propulsion unit outside the case. A case main body housing the engines and assemblies of peripheral parts of the engines, and a case cover covering an opening at an upper portion of the case main body are included. Mufflers are installed on an exterior of a lower surface of the case, and on the lower surface of the case, housing portions housing the mufflers and exhaust hoses are formed. | 05-10-2012 |
| 20160001867 | SPACER CASE FOR OUTBOARD MOTOR AND OUTBOARD MOTOR - In a spacer case for an outboard motor, a rear portion includes an upper fastening hole opening to the upper surface of the spacer case, into which a first fastening member is inserted, and a lower fastening hole opening to the lower surface of the spacer case, into which a second fastening member is inserted. At least one of the upper fastening hole and the lower fastening hole connects to a lateral opening inside the spacer case. | 01-07-2016 |
| 440077000 | Cowl | 6 |
| 20090215333 | OUTBOARD MOTOR - An engine is disposed in a top cowling. Burned gas produced in the engine is discharged to the outside through a first exhaust pipe, a second exhaust pipe, a third exhaust pipe, exhaust passage, and a exhaust passage. A catalyst is disposed to be housed in the first exhaust pipe and the second exhaust pipe. The first exhaust pipe and the second exhaust pipe are disposed in the top cowling. A fan is provided above the catalyst. As a result of this unique structure, a temperature increase in the cowling is prevented from being caused by heat radiated from the catalyst. | 08-27-2009 |
| 20090318038 | COWLING STRUCTURE FOR OUTBOARD MOTOR - In cowling structure for an outboard motor, a through hole is formed below an upper-cowling joining surface of a lower cowling; control cables are supported with a cable supporting groove of a back side plate, and the back side plate is fixed to the through hole; a sealing member that is covered on the outside of the control cables, is fitted into the through hole; a groove of a front side plate is placed around the control cables, and the front side plate is set onto the sealing member; and the sealing member is fixed to the lower cowling by a bolt together with the front side plate. The cowling structure for an outboard motor can prevent water intrusion by removing a notch on an upper-cowling joining surface of a lower cowling. | 12-24-2009 |
| 20100285705 | OUTBOARD ENGINE UNIT - An air intake passage system includes an external air intake port provided in a rear portion of a top cover and a cylinder section projecting upwardly from the engine cover for directing taken-in external air to the engine. The top cover is provided over the engine cover with a gap therebetween such that the taken-in external air is allowed to flow into the cylinder section and a water discharge section is provided between the engine cover and the top cover. Water, having entered together with external air, flows along the upper surface of the engine cover, bypasses the cylinder section and is then discharged via the water discharge section. | 11-11-2010 |
| 20120214367 | OUTBOARD MOTOR - In an outboard motor having an engine unit housed in an engine room formed by an exterior cover, a protruding portion is projectingly formed on the upper surface of an engine cover covering the upper portion of the outboard motor, and an outside air inlet opened to face forward is provided at the protruding portion. | 08-23-2012 |

| 20150017848 | Multi-Stage Watertight Chamber - A multi-stage watertight chamber is provided in this invention. The multi-stage watertight chamber comprises a first rotary seal, a second rotary seal, a first housing, a second housing, and an integrated shaft. The first and second rotary seals withstand external pressure to make sure watertight status is achieved when the integrated shaft rotates. The first housing forms a first watertight chamber. The integrated shaft protrudes through the first housing via the first rotary seal. The second housing is placed outside and adjacent to the first housing and forms a second watertight chamber. The first watertight chamber contains devices that must be isolated from liquid outside the first and second housings. The second watertight chamber is used to store water seeped through the second rotary seal and avoid causing damage directly to components and apparatus inside the first watertight chamber. | 01-15-2015 |
